Are you sure it sharpens? I have a similar setup due to my somewhat african-american hair. Grows in all directions and grows in. Used to have a TON of problems with various non-electric razors. Nowadays I do a pass with the trimmer part of the electrical razor and then with the razor itself. Works like a charm, no ingrown hairs. I don't go for a super-smooth shave, though.
